Final answer:
Typically, a salesperson can retain a summary document of an unsuccessful offer as part of their record-keeping duties, assuming compliance with relevant laws and brokerage policies.
Step-by-step explanation:
Whether a salesperson can retain a summary document of an unsuccessful offer depends on the laws and regulations governing real estate transactions and the policies of the brokerage firm. Generally, real estate agents are required to keep records of all transactions and correspondence, including unsuccessful offers, for a specified period. This is often dictated by state laws or real estate commission rules. The purpose is to maintain a transparent record in case of disputes or audits. In context, if the brokerage received the offer on behalf of the seller, the salesperson may indeed retain the summary document as part of their record-keeping duties. Therefore, the statement in question is likely true, assuming they adhere to the policy and regulatory requirements.
